Have used this Dometic product for years. Recently I went to West Marine where I purchased the product to find the label had changed. Same product number, same price BUT now recommends using 8oz to treat a 40 gallon tank instead of 4oz. I emailed Dometic and got the following response:

I am sorry about this inconvenience. Due to the fact that we have tested these units we have come up with some newer solutions and the amounts may have varied to be better affective. We appreciate this opportunity to address your situation and hope all of your future travels are trouble free. Please do not hesitate to contact us at any time to order parts or for further assistance.Sincerely,Gabi

So, I wonder if the formula is the same or am I going to have to use twice as much to treat my holding tank for the same price (at effectively twice the cost)? I guess I will have to see!
